T0 all whom t may concern.'

VBe it vknown that I, WILLIAM SEARS WHITE, a citizen of the United States, and a resident of Denver, in the county OfDenver and State of Colorado, have invented anew and Improved Flushing-Valve, of which the following is a description. Y 1 y My invention relates Vto flushing Lvalves and is more particularly designed as an improvement on the flushing'valve forming the subject matter vof United States Letters PatentrNo. 1,207,353 granted to me December 5',

Theflushing valve ischaracterized by a reservoir or container havingan inlet and an outlet, communication between which .is controlled by a valve, preferably apiston valve.

An air chamber is provided preferably di- -rectly associated with the reservoir structure and .communicates withthe top .of thelreservoir above the piston valve through. the .medium of'a vertical passage. The arrangement is such that in operation -of the valve the reservoir will be vented above the valve topermit the flow of water thereinto asthe valve opens, and whereby as-thevalve closes vair may pass'from the airchamberto ithe'top of the reservoir as the water reced'esfrom the latter. After .the closing of the piston valve and the cutting OE of the wateriinlet, the remaining'water in andfbelolw the ai'r chamber will Vserve for thel relill'of the vbowl or'other'lixturen f p I. T

1 The present invention" relates especially-to Ycertainimprovements including an annular Ychambery about th'eimainA chamber andreceiving vthe water vfrom the inlet to prevent one-sidedlpressure; means to choke theoutlet with the operation of the main valve, and auxiliary means to create al siphon action in a bowlor other xture in situations-where the water supply issmall, all as hereinafter particularly explained.

Y Reference is to be had to .theaccompany-` ingdrawings forming a part of this specilication. i fr:

In constructing a practical embodiment of kthe invention in accord-ance lwith the illus-vv trated example, a reservoir or containery 10 is provided having'a .cylinder 10, in which a valve 11, preferably: apistonvalve, is movable. An inlet 12 leads to the interior ofthe reservoir, and anoutlet 13 is provided atathe end .of the passagelis a valve seatv16,-and

a suitable disk 17,-Or1the like Ais applied to the bottom of thepiston valve 11 and secured by a serewlS lor the like.

In the present embodiment-offmyinvention I provide, `for unseating fthe valve, a

tripk linger y,19,fsaid linger being pivoted on a rockablef'choke jplate 20 mounted: on a shaft- 21, the said plate being connected Vwith a rock shaft 22 through the medium of a sleeve 23 on; said shaft having Aoni arm 24 connected by a link-25 with the saidrockable chokep-lateu. y .y .l

An annular'zain chamber 26. is produced between .the tubular innerr shell 15' and Athe main shell ofthe reservo-ir'lO, andcommunif ycation between1sa1d chamber and said reservoirabov-e the piston 11', is established as follows :v Alvertical air passage 27 communi- `cates at its lowerfend withfthe air chamber :26 and communicates through` a port 28and valve chamber 291with an auxiliary chamber v30a`bovethe cylinder 10%, and connects with the latter through a tubularneck 31'. The

valve 32- controls the port ..28 andV has ay depending stem 33 extendinginto the vertical passage -'27 Alsoya valve 34 seatsfon the upper :endof the neck 31 and controls communication between the auxiliary chamber 30 and thefcylinder 10a. An extension sleeve 35 is slidable on theneck 31 andnormally` lgravitates to fazposition' directly below said neck 'to' be engaged by a valve 361on the piston 11. To open theavalve ;32 simultaneously withithe raising ofthe piston valve 11, a bar 37 is disposed in the by-pass 27 and its v upper end is directly adjacent the stem 33 on the valve 32, while the lower end of said bar 37 rests on a rocker arm 38 on the shaft 22. The rock shaft 22 may be operated in any suitable manner, there Ybeing indicated a handle 39 for the purpose. Y y g In practice when the piston valve 11 is in the closed position, the chamber 26 is lled with air. When the 'handle 39 is raised the auxiliary valve 32 and the piston valve 11 will both be raised from their seats. At the same time` the disk 20 will be swung hori- Zontally to partly close the passage 15, causing the water from inlet 12 to follow upward into the cylinder 10a, and through the neck 31, chambers 30 and 29, andfport 28, and downward through the passage 27 and outlet 13 to the bowl, it being understood that the piston valve 11 has not a tight-fit in the cylinder 10a, vbut permits the flow of a limited quantity of water around said piston valve and to the chamber 30. The upward pas sage of the water in the cylinder 10 carries the piston or equivalent valve 11 upwardly to the top of the cylinder 10a. The ascent ofthe piston is very rapid and if allowed to continue unchecked until it strikes the top of the cylinder 10a will produce a disagreeable noise. The sliding sleeve 35vprevents the free movement of water into the chamber 30 after the valve 36 engages and closes the bottom of the neck 31, but it permits the piston valve 11 and sleeve 35v to ascend slowly after engagementof said sleeve with the valve 36 and the water cushion is displaced. When the handle or lever 39 is released the passage 15 is lopened and the valve 32 allowed to seat. The water now rwill flow from the inlet 12 and the annular chamber 14 directly throughthe passage 15 to the outlet 13.- The passage 15 being larger than the outlet 13 and the inlet 12, allows free movement o Vwater through said passage which chokes the smaller mouth of the outlet 13. This causes a pressure below the body of air in the chamber 26 whichvis almost, if not quite, equalto the'pressure in the cylinder 10a and chamber 30, and causes the air to pass from the air chamber 26 through theV passage 27, causing the check valve .32 to lift, so that the airl passes through the valve chamber 29, to the chamber 30. The .valve 34 has guided movement in a stem 34a threaded into the top of the chamber 30 as at 34h, whereby to regulate the opening between the valve Y34 and its seat 34c so that the period ,of flushing can be employ a substitute for a stuffing xbox,

whereby to prevent the tightening of the vpacking nut 40 to a degree to cause the shaft to be bound. For the purpose a rubber sleeve 41, which, initially,'is of thegeneral form of a nipple of a nursing bottle, isV placedon theshaft, and fitting on the shaft within the sleeveu41 is aanged'collar42. The anged collar 42 and they corresponding ange 43 on sleeve 41 are clamped between VtheV nut 40 and the adjacent threaded boss 40'LL on the reservoir 10 through which the shaft 22 passes. The rubber sleeve 41 has an expanded zone 41a near the inner end so that the extreme inner end tightly hugs the shaft to give a tight joint, while at the same time the nut 40 will securely clamp the said sleeve 41.and the collar 42V in position and Will prevent the nut from binding against the usual collar or flange 44 o n the shaft. Y

In situations where the water supply is small and where it is necessary Vto furnish a volume sufficient to create a siphon actionin a bowl or other fixture, an auxiliary pipe-49 may ybe employed communicating withla pressure Ytank 50 and communicatingy with both the main supply pipe 52 and inlet pipe l 12 of athe reservoir. Y When this Vattachment is employed the auxiliary chamber 30-com'- -municates by a recess 45, a port 46,-;a

coupling section 47, and pipe 48nwithvthe said auxiliary pipe 49. The-port46`is controlled by a-ball valve 51 or-,the like in the coupling section 47. Itis a-we'll known vfact f .cause the air which has passed from theair Vchamber 26, to chamber 30, Ywhile the flushing valve vis Yin operation, willfindv its way through the pipe 48 and its connections with said chamber 30 to the auxiliary pipe 49 after the pistonvalve '11 is l seated. The ball 51 lbeing'fo'rced'against its seat prevents too much water returning? lfrom the auxiliary pipe 49' through the pipe 48 when the piston valve 11 is open.- 1 The coupling 47 affords a ready means of gaining access to the valve 51 and its'seat.

13 the rising of the water in the air chamber 26 will seal said chamber. Thisk results in the alternate passageof air between the Ysaid air chamber and thechamber. 301 and cylinder 10a, and a quantity of water is insured in the lair chamber in addition to any water remaining below the same to act as a refill of a bowlfafter flushing. lThe construction also results in preventing what is known as a water hammer.

In the choking of .the mouth of the outlet In practice I indthat the water from con- 'j' Y tainer 14 exerts a suction or pull on piston 11 as said water passes into passage 15 this with .theaid of ,-a back pressure due to the water being retarded at flush rim of a bowl or other fixture will produce the same effect that a small opening 13 will do.

Having thus described rnyl invention,- I claim as new, and desire to secure by Letters Patent l. In a flushing apparatus, a reservoir adapted to contain flushing water and provided with an inlet, and an outlet, an air chamber incommunication with the outlet adapted to be liquid-sealed by the iushing water to cause a quantity of water to be held by the air chamber for the refill of a fixture, and means to direct the air in said chamber to the reservoir at the top of the latter in discharging the reservoir,l and for directing air to the air chamber from the reservoir in the filling of the latter; together with a pressure tank, a pressure pipe connecting with the pressure tank and with the inlet of the iushing valve, and connections between the said pressure pipe and the reservoir at the top of the latter whereby to renew the air in the pressure tank and pipe from the flushing valve.

2. A flushing valve including a container having a water inlet, a water chamber with which the inlet is in communication, a discharge outlet from which water may How from the water chamber, a vertically movable valve in the water chamber and controlling Copies of this patent may be obtained for lthe unseating of the first-mentioned valve.

3. A flushing valve including a container `having an inlet, and an outlet; a water chamber in communication with the said inletv and outlet, a vertically movable valve in said chamber controlling the inlet, an auxiliary chamber above the water chamber, an air chamber, passages establishing communication between said auxiliary chamber and the air chamber, means controlling communication through said passages, and means establshing communication betweenthe auxiliary chamber and the water chamber, said means including a vertically slidable tubular member at the top of the water chamber, together with a member on the vertically movable valve to engage said vertically slidable member.
